 collected, and there is still some uncertainty as to its true 

 place among the Cruciferte. It has already been referred 

 to several genera, and Dr. Robinson has only doubtfully 

 named it Thelopodimn. He says : " The problematic 

 S. salsugineiim, Pall, with glabrous entire cordate-clasping 

 leaves, purplish flowers and undivided stigma, may well 

 be referred to Thelopodiuni, from which it appears to 

 be distinguished only by its small size and slender 

 habit." (Syn. Flora, p. 137). Its range in America, 

 according to Dr. Robinson, is " Rocky Mountains from 

 Colorado at South Park, Porter, to British America and 

 shores of the Arctic Sea, Richardson, according to Hooker, 

 I.e.," but it has never been found in our Rocky Mountains 

 so far as we know.
